Takashi Kunihara
The two major valve-sparing root replacement procedures, aortic valve reimplantation (reimplantation) and aortic root remodeling (remodeling), have advantages and disadvantages, which are reviewed herein. The main advantage of reimplantation is the resulting annular support, and the disadvantages are the unfavorable hemodynamics and relatively long procedure time. The main advantages of remodeling are the physiological hemodynamics and decreased procedure time, and the disadvantage is the lack of annular support...

BACKGROUND: Coronary button reimplantation can represent a technical challenge of aortic root reconstruction that can be associated with significant morbidity and mortality. With the goal of simplifying coronary reimplantation and reducing the incidence of related complications, we designed a new Dacron graft with prefabricated coronary branches to minimize coronary artery mobilization and prevent the potential mechanical complications of reattachment to the body of the graft. METHODS: Between June 2010 and May 2012, we implanted the graft in eight patients (six males, two females) ranging in age from 42-68 years (mean, 54 years)...

OBJECTIVES: The aortic valve-sparing David procedure has been applied to the elective treatment of patients with aortic aneurysms with excellent results. The use of this technique in patients with acute aortic dissection type A (AADA) is still a matter of debate. We present our long-term experience with 109 patients with AADA who had the valve-sparing David I procedure. METHODS: Between July 1993 and October 2015, 109 patients with AADA had the valve-sparing David I procedure at our centre...

Circumferential dissection is a rare clinical condition of aortic dissection, which is also known as intimo-intimal intussusception. In patients with type A aortic dissection with intimo-intimal intussusception, disruption and prolapse of the intimal flap into the left ventricle may occur and cause severe aortic regurgitation or blockage of the coronary artery ostium. A 43-year-old man presented with sudden dyspnea. Echocardiography revealed severe aortic insufficiency. Acute coronary syndrome was also suspected, but coronary angiography showed normal coronary arteries...

The regurgitation of the native aortic valve in patient with previous David operation may represent a clinical challenge because the morbidity and mortality risk of re-operation is not negligible. Here we describe the case of a patient suffering from late severe aortic regurgitation, many years after David operation, efficaciously treated with transfemoral transcatheter aortic valve implantation. To the best of our knowledge, this is the first description of such treatment in a patient with aortic regurgitation and previous David operation...

Marfan syndrome is an autosomal dominant connective tissue disorder that affects multiple systems, including the skeletal, ligamentous, oculofacial, pulmonary, abdominal, neurological, and cardiovascular systems. Cardiovascular complications, which involve the aorta and aortic valve, contribute most significantly to patient morbidity and mortality. A literature review was conducted on pathophysiology of the disease and recommendations for early diagnosis and treatment. Diagnosis largely relies on clinical features and a thorough history...

In recent years the use of valve sparing techniques has become more common in selected patients with aortic valve insufficiency. However, limited experimental research has been performed to document the biomechanical effect of these techniques. One experimental platform is to evaluate how the normal physiological aortic root forces are altered or re-established after the surgical intervention. Hence, the aim of this project was to develop new implantable force transducers for a biomechanical description of various aortic root repair techniques...

Aortic aneurysms requiring surgery in early childhood are rare. Herein we describe the case of a three-year-old with massive aneurysmal aortic dilation secondary to the rare and often lethal genetic disorder, cutis laxa. Initial thoracic aortic aneurysm gene panel was negative. Parents of the child were not known to be consanguineous, but high-density SNP array revealed several regions of homozygosity. This prompted targeted sequence analysis that identified a novel homozygous missense mutation in the gene for cutis laxa, EFEMP2...

Aortic regurgitation (AR) is a life-threatening complication of Takayasu arteritis (TA). Takayasu arteritis is a large-vessel vasculitis with a predominance in young adolescent and adult females. Inflammation involves the aorta and its major branches resulting in arterial dilatation, stenosis, aneurysm, occlusion, and thrombosis formation. Pediatric TA cases have been reported to also cause severe complications such as coronary aneurysms, retinopathy, and hypertension due to renovascular stenosis. In this report, we present a rare occurrence of infantile TA with severe AR requiring surgical intervention after failing medical therapy...

BACKGROUND: Valve-sparing root replacement (VSRR) is an established therapy for aortic root pathology. However, late aortic valve dysfunction requiring reoperation remains a primary concern of this procedure. This study examines risk factors for late aortic insufficiency (AI) and aortic stenosis (AS) after David V VSRR. METHODS: A retrospective review from 2005 to 2015 at a US academic center identified 282 patients who underwent VSRR. Cox proportional hazards regression analysis was used to identify risk factors for late AI and AS after VSRR...

OBJECTIVE: Although aortic valve-sparing operations are performed throughout Japan, the indications, specific repair techniques, and outcomes have not been reported in full. Thus, we conducted the first nationwide survey of aortic valve-sparing surgery. METHODS: We mailed a questionnaire to 508 institutions across Japan to obtain information on elective aortic valve and aortic root surgeries performed in 2014. Included in the mailing was a secondary questionnaire that sought further information from institutions reporting aortic valve-sparing surgeries...

INTRODUCTION: A cell salvage device is used in cardiac surgery with the aim of reducing allogeneic blood transfusion. Suction of blood from the operating field used for the device is often accompanied by diathermy smoke. There is limited published research to know if this blood is then contaminated with clinically significant levels of harmful chemicals from this smoke. Postoperative cardiac surgery patients are already physiologically vulnerable, making the optimization of salvaged blood worth considering...

OBJECTIVES: The first publication of Loeys-Dietz syndrome (LDS) described aortic rupture at young ages. Experience with new LDS types showed that the clinical course varies, and thresholds for prophylactic surgery are discussed. As this is an uncommon disease, experience needs to be shared. METHODS: Retrospective review of patients with LDS types 1-4 undergoing cardiovascular surgery during the years 1991-2016. RESULTS: Thirty-five patients (including 6 children with LDS2) underwent 57 operations...

Quadricuspid aortic valves (QAVs) are extremely rare. In this case study, we report a David-V valve-sparing aortic root replacement with reimplantation of a native QAV in a patient with aortic dilation, normal valve function, and a family history of aortic dissection. Microscopic pathological examination of the excised section of the aorta revealed scattered small foci of cystic medical degeneration throughout. A genetic predisposition for aortic dilation may be present in patients with QAV, even in the setting of a competent valve...
